I see some people here hoping a 100x with some big coins, but this is impossible.
Take a look to the market cap, and make some maths to see.
For me, a potential coin for a 100x must have a market cap below 10m usd currently, as it can't go much higher than 1billion usd. Digibyte is a great example for that, it came back from deep darkness.
I don't have any idea of which coin can do a 100x currently but it can't be one of the famous one (this would be too easy
). A lot of coins become famous only after it already did a 10x and then it's almost impossible to do another 100x after.
I think it's easier to find 10 potential 10x coins than finding one 100x coin.
